ParsePlugins 已经初始化错误

Question

我正在使用解析推送通知我收到以下错误

    Caused by: java.lang.IllegalStateException: ParsePlugins is already initialized

        at dalvik.system.NativeStart.main(Native Method)

这是 ParseUtils 类

 public class ParseUtils {

private static String TAG = ParseUtils.class.getSimpleName();

public static void verifyParseConfiguration(Context context) {
    if (TextUtils.isEmpty(AppConfig.PARSE_APPLICATION_ID) || TextUtils.isEmpty(AppConfig.PARSE_CLIENT_KEY)) {
        Toast.makeText(context, "Please configure your Parse Application ID and Client Key in AppConfig.java", Toast.LENGTH_LONG).show();
        ((Activity) context).finish();
    }
}

public static void registerParse(Context context) {
    // initializing parse library
    Parse.initialize(context, AppConfig.PARSE_APPLICATION_ID, AppConfig.PARSE_CLIENT_KEY);
    ParseInstallation.getCurrentInstallation().saveInBackground();

    ParsePush.subscribeInBackground(AppConfig.PARSE_CHANNEL, new SaveCallback() {
        @Override
        public void done(ParseException e) {
            Log.e(TAG, "Successfully subscribed to Parse!");
        }
    });
}

public static void subscribeWithEmail(String email) {
    ParseInstallation installation = ParseInstallation.getCurrentInstallation();

    installation.put("email", email);

    installation.saveInBackground();

    Log.e(TAG, "Subscribed with email: " + email);
}
 }

我已将此作为参考http://www.androidhive.info/2015/06/android-push-notifications-using-parse-com/

这是我的应用程序

 public class MyApplication extends Application {

private static MyApplication mInstance;

@Override
public void onCreate() {
    super.onCreate();
    mInstance = this;

    Parse.initialize(mInstance, AppConfig.PARSE_APPLICATION_ID, AppConfig.PARSE_CLIENT_KEY);
     //register with parse
    ParseUtils.registerParse(this);

}


public static synchronized MyApplication getInstance() {
    return mInstance;
}
 }

请帮忙。

从oncCreate()中删除下面的初始化

 Parse.initialize(mInstance, AppConfig.PARSE_APPLICATION_ID, AppConfig.PARSE_CLIENT_KEY);

因为你已经在里面初始化了

ParseUtils.registerParse(this);
